“…This method exhaustively regards the potential risk of heavy metals in soil or sediment [9,35]. PERI was designed to assess the heavy metal content toxicity of trace elements in soil or sediment, the kind of pollutant and the toxicity level of heavy metal pollution.…”

“…Contrary to the majority of organic pollutants that have lost toxicity due to biodegradation, they can cause long-term toxic effects since metals are not degraded [6,7]. Also, depending on the physicochemical characteristics of the soil, such as ORP, pH, conductivity, soil texture, organic matter and organic carbon, heavy metals may enter from the soil to the aquatic ecosystem and contaminate the drinking water system [8,9]. Heavy metal pollution in soil has become an important problem worldwide and researchers have focused on this pollution [10][11][12][13].…”

“…On the other hand, the ecological risks of heavy metals in soil can be examined using many different pollutant indexes [5,9,[21][22][23][24][25]. In these studies, the ecological risks of heavy metals were assessed by total concentration of the metals in soil or sediment.…”

Sapanca Lake is an important drinking water source located by D-100 highway in the north and E-80 (TEM Anatolian Highway) and a railway line in the south. Heavy metal concentrations in roadside soils result from vehicle exhausts and the corroding metal parts of vehicles. Due to the difficulty of removing heavy metals from the soil, a significant pollution problem arises and this pollution also affects the water resources by means of rain. Although there are several industries, the highway located near the lake is the most important pollutant source for Sapanca Basin. Therefore, this study evaluated heavy metal concentrations, the chemical fractions of the metals and ecological risks (by using C f , RAC and PERI) in the soil samples collected seasonally between 2015 and 2017 in Sapanca Lake Basin. Al and Fe were determined at very high amounts in all stations and the relationship between mean concentrations of other metals was determined to be Zn>Ba>As>Ni>Cr>Pb>Cu>Co>Cd. However, Zn, Ba, As, Ni, Cr, Pb, Cu, Co and Cd mean concentrations were determined as 87.63 mg/kg, Ba 86.87 mg/kg, 80.40 mg/kg, 58.62 mg/kg, 50.42 mg/kg, 41.90 mg/kg, 38.16 mg/kg, 13.98 mg/kg, 2.89 mg/kg respectively. Al, Fe, Co, Cr, Cu, Ni and Zn are mainly found in residual fractions in soil. According to the environmental risk assessment on the basis of soil stations, the 7 th station has the highest GC f value, which means that the soil sample presents the highest environmental risk according to the contamination factors. On the other hand, Cd has serious potential ecological risk and As has considerable potential ecological risk in all stations.

“…The PCA is used to reduce several potential indicators to a smaller set of comprehensive ones. It is also used to further evaluate the relationships between and sources of the metals [67]. The results of PCA analysis in this study were used to assist the source identification of trace elements and are shown in Table 7.…”

Seasonal and Spatial Distribution of Soil Trace Elements around Kitchener Drain in the Northern Nile Delta, Egypt

et al. 2019

The pollution of agricultural soils, water and plants by trace elements (TEs) in the Nile Delta Region, Egypt, is of great importance. This study aimed to investigate the spatial and seasonal variation of some TEs in the agricultural area adjacent to Kitchener Drain and to evaluate the ecological risk posed by these elements using six indices. Soil and plant samples were collected from seven sites close to the drain, while water samples were collected from the corresponding sites inside the drain during three seasons (winter, spring and fall). The results showed that all studied TEs in the soil varied seasonally and spatially among the locations around the drain. Most of the studied elements in the soil were higher in the southern and middle area around the drain. All studied elements in the soil were also higher in the winter than other seasons. Nickel and lead were almost non-detected during all seasons in plant tissues, while other elements were higher in the winter than other seasons. In contrast to the soil and plant tissues, water samples demonstrated lower or non-detected levels of TEs. The results also indicated that the values for the risk assessment indices differed among the studied TEs. Therefore, there is a risk of increasing the concentration of some metals in the study area due to anthropogenic pollution from the adjacent polluted drain through irrigation with contaminated water and spreading of contaminated dredged materials on agricultural fields.

“…As an essential trace element, Cu pollution, especially its soil pollution, was not payed enough attention in past. However, more attention is paid on the trace element copper pollution in soils with the great investigation of soil environment [4][5][6]. For example, Keiblinger et al [7] found a strong negative effect of Cu application on the total abundance of soil microbial biomass and the fungal biomass proxy ergosterol at relatively low concentrations.…”

To investigate responses difference of soil potential nitrification rates (PNR) to heavy metals and antibiotics, batch toxicity experiments of Cu and sulfadiazine (SDZ) were conducted in four typical soils which were collected from different locations of China. Toxic differences of Cu and SDZ to soil PNR were evaluated based on their values of EC 20 and EC 50 calculated with logistic model. It was found that soil nitrification was a good indicator of Cu contamination in soils except for paddy soil. For SDZ, their EC X values were significantly higher than its concentration level (0.002~0.760 mg·kg -1 ) in soils. Thus, it was concluded that soil nitrification might be more sensitive to Cu than SDZ in field soil. The further Pearson correlation analysis indicated that the response of soil PNR to Cu and SDZ contamination were significantly related with soil PNR 0 and pH. ARTICLE HISTORY
